Black Tank (s)

[Jupiterd1]

We have a 360PDEK 2015 and the control panel has a BLK switch 1 on top and 2 on the bottom!! I think we only have one black tank but I am not sure!! Outside at the tank panel there is only one black tank wash out and only one dump valve black tank handle!! Back to the inside control panel one shows full and the other shows empty!! Can somebody tell us how this works or is there only one Black tank??? Thank for your help and God Bless!!! Dave, Vicki & Buddy (fur baby)

It's a universal monitor panel.
My 320rs only has one black tank as well, but has 2 black tank tank monitors.

Btw how many pull handles do you have?

Reason I ask is my sabre in one model had a 1/4 bath in the back but my model didn't and had an outside kitchen so they left the black tank in place for the outside kitchen sink.

You have only one black tank, one grey and one galley. The monitor will be tank one.
